This fluid and uncertain political scene provides a unique moment to explore the dynamics of UK political parties and the key challenges facing them as they grapple with the changing shape of politics in 21st century Britain. Key questions explored in this book include:

• How far have Labour and the Conservatives escaped from the shadow of Thatcherism?
• What turned the Liberal Democrats from a party of protest to a party of power?
• To what extent have green and far-right politics entered the political mainstream?
• What impact, if any, has devolution had on party lines across the UK?

Moreover, at a time when trust in politics has hit an all time low, political parties are facing a crisis in confidence. Membership of mainstream parties has melted away, while support for pressure groups in areas such as the environment and human rights has grown. At the same time, parties rely on hired professionals to win support among the growing number of independently-minded voters. In understanding how political parties have become much more aggressive, professionally-driven organizations, this book points to real concerns about their capacity to engage and mobilise an increasingly critical and disenchanted electorate. British politics needs strong parties, but to regain voters' trust, they need to change.
